Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a double release of memory during the error path in the RDMA vmwpvrdma driver’s pvrdmaallocuconte...

CVE-2026-45964

A flaw was found in the Linux kernel's SUNRPC Sun Remote Procedure Call gssauth module. An issue in the error handling path for gssallocmsg could lead to a kernel reference count kref leak. This occurs when a memory allocation fails, preventing the proper release of the gssauth structure. A local...

CVE-2026-45978

A flaw was found in the Linux kernel's Greybus Lights subsystem. This vulnerability occurs when the gblightslightconfig function attempts to store a channel count before successfully allocating the corresponding channels array. If the memory allocation fails, a subsequent cleanup operation can tr...

CVE-2026-45981

A flaw was found in the Linux kernel, specifically within the s390/cio component. This vulnerability stems from incorrect device lifecycle management during subchannel allocation. This could allow an attacker to trigger use-after-free or double-free conditions, potentially leading to system...

CVE-2026-45998

A flaw was found in the Linux kernel's rxrpc subsystem. This vulnerability arises when the system attempts to unshare a packet buffer, and the operation fails due to an allocation issue. This failure can lead to a Use-After-Free UAF condition, where the system attempts to access memory that has...

CVE-2026-48065

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, src/conf.c allocates heap memory proportional to ndevices, a count derived from libxml2 XPath evaluation of the config file, without first enforcing an upper bound. On 32-bit targets armv7l, i686 --...

CVE-2026-47271

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, src/mem.c implemented out-of-memory guards for xmalloc, xrealloc, and xstrdup using assertdata != NULL. The C standard specifies that all assert expressions are compiled out when NDEBUG is defined at...

CVE-2025-36122
